Possible Malware (?) – Firefox “Secure Connection Not Available” alert


Hi, I use Firefox as my browser. I am very careful and aware of which links I click and I don’t do dodgy things (aka pron lol) on my laptop. I have been getting the following message on a number of sites that use HTTPS verification:

 

HTTPS-Only Mode Alert Secure Connection Not Available

 

I have noticed a few things that be helpful. Firstly, if I go to my banks URL, I get that message. When I google my bank name, the results give me a “sign in” option. If I click that I can sign in alright even though it is also HTTPS enabled. Odd.

The other thing of note is that I do not have these problems in Chrome, just in Firefox. I am uncertain if this is an oddball Firefox issue or if I have a “man-in-the-middle” malware situation. I have done a virus scan using Windows Defender, AVG, and Bitdefender and all came back clean.
